Marizanne Kapp has progressed to become one of South Africa Women's premier all-rounders since making her international debut at the 2009 World Cup in Australia. She holds the record for the highest-ever score by a South African at Women's World Cups: 102* against Pakistan at Cuttack in 2013. During the course of her innings, she also forged a 128-run stand with Dane van Niekerk, which is the highest-ever partnership for South Africa Women at a World Cup. She took 3 for 18 with her medium pace in the same game to ensure her side progressed to the Super Sixes stage.

A talented athlete who has also represented Eastern Province in netball and athletics, Kapp has been at the forefront of South Africa's resurgence since 2014. She starred with 23 and three wickets in South Africa's maiden victory over New Zealand in women's internationals, at Women's World T20 that year, which helped them qualified for the semi-finals for the first time in the tournament's history. She also became just the third woman to take a T20I hat-trick, against Bangladesh in September 2013.

Having finished a degree in sports management, she became one of the beneficiaries of Cricket South Africa's contract system that came into force in October 2013. In 2015, she was one of only four South Africans to feature in the inaugural Women's Big Bash League. She finished the tournament with 17 wickets for runners-up Sydney Sixers, at an economy rate of 4.28 runs per over - the best in the competition.
